A 2026 study of 135 environmental samples — lettuce, irrigation water and organic manure — from market garden sites in Bobo-Dioulasso, Burkina Faso, testing for methicillin-resistant Staphylococcus aureus (MRSA) by microbiological isolation, antimicrobial susceptibility testing and molecular characterisation. Of 55 Staphylococcus isolates, 16 (32.7%) were confirmed MRSA, with the PVL toxin gene detected in 18.4% and TSST-1 in 6.1%; resistance to oxacillin reached 96.4% and to fusidic acid 69.1%. The authors call for stronger microbial surveillance, better hygiene protocols and policy measures to reduce foodborne risks associated with urban agriculture. The study is West African evidence that market gardens, while supplying food and income, can also act as environmental reservoirs of antimicrobial-resistant bacteria via irrigation water and organic fertiliser.
